HE MAY have been one of the show's main characters, but it has been reported that William Fichtner may not be returning to the Prison Break reboot.

Fans of the hit show are eagerly anticipating the fifth season, but there are still gaps in the puzzle where certain characters/actors are concerned.

According to Movie News Guide however, the debate about whether or not actor William Fitcher will be reprising his role of Alexander Mahone is over. And it's not good news for those wanting to see his return.

While much of the press surrounding the series has held out hope, this one source has allegedly had it "confirmed" that the actor won't make an appearance in season five.

Mahone became a breakout character from season two onwards and despite being a villain at first, he soon became a fan favourite.

Fichtner was originally only contracted for seasons two and three, but was eventually convinced by producer Matt Olmstead to come back for the fourth.

However, it would seem that he hasn't been tempted by the potential to appear in season five.

The character was rendered a little redundant in the show's final season, but was still around for the fans. By the end of the series he had totally sided with the Schofield brothers and even turned down the chance to return to the FBI if he sold out his crew.
